Many people camped overnight to make sure they were in with a chance of getting a ticket today

Forecaster Oli Claydon told The Sun Online: "It may be that nowhere does see that much rain, but that is the limit of what we might see if showers are persistent and there's shower after shower in the same place."

The yellow warning is in place from 6am tomorrow to 2am on Friday across a large section of the country.

The Met Office warning adds: "While these storms may miss many places, where they do develop intense downpours are likely, bringing the threat of sudden flooding of roads, transport routes, homes and businesses.

A Met Office spokeswoman added: "As the days go on and the heat continues we will see some thunder storms eventually and these are the one we are concerned about."

She said two main storms will sweep over the country - but with some parts simply seeing looming clouds, and others being affected by rain and possible hail.
